sheath. “Control” and “power” cable networks must be kept separate.
Specific conditions
Electrical safety parameters:
Circuit inductance Lint. y 1 mH
Circuit capacity Cint. y 283 nF
Maximum supply voltage Usupp. = 24 V DC
Specific conditions for safe usage:
The equipment must be connected to an intrinsically safe device certified for electrical output characteristics
that are compatible with those listed above.
The voltage source connected to the switch must be of a type certified for use in group IIC, IIB or IIA explosive
atmospheres, and its output circuit must becertified intrinsically safe. External circuits connected to the switch
must be certified intrinsically safe for use in explosive atmospheres, and their use must be compatible in terms
of intrinsic safety.
Care shall be taken not to install the equipment where propagating brush discharge may occur.
Servicing and maintenance
Before the device is restarted, the requirements listed on page 1/2 of the “Operation” section must be complied
with. The intervals for carrying out servicing and maintenance must be set according to the environment and
climatic variations.
Do not open or remove the cables of live devices.
Ensure that the device does not become covered in layers of dust: please vacuum regularly using0
equipment appropriate to the zone.
Check the condition of the fixing supports.
Check the following points on a regular basis:
the mechanical adjustment of the product,
wear: the devices must not be used in excess of their catalogue specifications,
check that the electric switching functions correctly,
the devices must not be modified,
The following items must be checked at least once a year or following a lengthy stoppage period:
All external parts must be undamaged,
the position switch. If damaged, replace it,
the fail-safe loop,
the mechanical condition of the switch and the connecting devices,
Every 100,000 operating cycles or every 10,000 hours: the condition and operation of the actuating devices. If
any of the items checked is defective, it must be replaced immediately. If the devices are used at the limits of
the temperature (-20…+60 C° / -4…140 F°) and humidity (50 to 95 %) ranges, check the integrity of the
connecting devices at regular intervals.
Device shall be cleaned using a damp cloth, compresed air must not be used.
